Description
A small cephalaspidean reaching about 9 mm in shell length. The shell is thin, fragile, pellucid, white or greenish, rather obliquely oval, smooth, somewhat roughened by striae of growth, imperforate. The aperture is narrow posteriorly and dilated anteriorly; the lip is somewhat involute; the columella is callous on its lower part. Pease's type was 9 mm long and 6 mm wide. In life the ground colour of the animal is pale watery green, closely dotted with orange and purple. The portion seen through the shell is spotted obscurely with cream-yellow, the margins powdered with white. The foot is cream-white, remotely dotted with pale orange. The side lobes do not extend back over more than one-half of the shell. The foot is regular in width and rather sharply rounded behind.Distribution
Indo-Pacific to the central Pacific. Type locality: Tahiti, Society Islands, based on a specimen collected by Andrew Garrett and described by Pease. Subsequently recorded from the Hawaiian Islands, southern Japan, the Philippines, Indonesia and other western Pacific localities.Etymology
The specific epithet ovalis is the Latin adjective meaning "oval", in reference to the somewhat obliquely oval shell shape. Pease did not state an etymology, but the meaning is consistent with his "T. ... suboblique-ovali" in the opening of the description.Remarks
Originally placed by Pease in Haminea. Pease noted at the head of the paper that "the animals of the following series of Bullidae and Nudibranchiata were drawn from life by Mr. Andrew Garrett, and may be relied on as being accurately and faithfully represented". The species was later transferred to Lamprohaminoea; the parentheses in the author citation reflect this generic transfer. The Japanese name "キホシミガキブドウガイ" ("yellow-starred polished grape-shell") refers to the yellow star-like flecks and the highly polished, grape-like appearance of the shell.References
